Contains a record describing the attributes of each QSO Base object and also best Surrogates to fill in the QsoConcordanceAll view.

This table is copied from the 'base' Best..PhotoObjAll Table. It has a row for each object flagged as a QSO (a candidate) and if no candidate exists nearby a Spec or Target candidate then a 'surrogate' Base object is added -- the closest Best within 1.5 asec of the QsoBunch head. If no such surrogate best object can be found, we use the ZERO surrogate (literally, all fields are zero). The test for a best object being a QSO candidate is: primary target flags set to one of TARGET_QSO_HIZ |TARGET_QSO_CAP | TARGET_QSO_SKIRT |TARGET_QSO_FIRST_CAP | TARGET_QSO_FIRST_SKIRT The table also includes the id and summary statistics for matching FIRST and ROSAT objects if they exist, and zero otherwise Includes the absolute magnitude based on Pen (1999) and Pei (1999) if a reliable reshift is available from a specobj object in the bunch.
